无线视频传感器网络由嵌入摄像感知装置的无线传感器节点组成。节点可以获得图像视频等更加直观的客观物理量,通过参数标定直接获取目标位置坐标,实现快速精准的目标定位。相比传统传感器网络, WCSN使得目标跟踪内容更加丰富。基于WCSN的特点,提出了运动趋势动态分簇目标追踪算法。该算法在网络中形成一个动态簇,根据目标的移动而动态更新簇内成员,选举新簇头对目标进行追踪,直到目标走出监测区域。仿真实验结果表明,WTDC算法较传统目标追踪方法计算简单、效率更高。

Wireless Camera Sensor Networks ( WCSN ) is conposed of wireless sensors embedded with camera perception devices.The sensor can not only acquire direct objective physical quantities such as image video, but also the coordinates of target through parameters calibration to implement rapid and precise target localization.Target tracking can be applied with richer applications com-pared with traditional wireless sensor network.Based on the features of WCSN, a Moving Trend Dy-namic Clustering( MTDC) target tracking algorithm is proposed.MTDC generates a dynamic cluster in the network, updates its cluster members according to the moving situation of the target, and e-lects the new cluster head to track the target until it gets out of the monitoring area.The simulation results show that MTDC has certain precision and better efficiency in target tracking compared to oth-er traditional algorithms.
